The k6 API and CLI are easy-to-use, flexible and powerful.
Write tests in Javascript that mimic real-world scenarios.
DevOps & SREs
Automate your tests to ensure that your infrastructure and application remain performant.
Configure SLOs in your k6 script to test the health of your services.
Software Testers & QAs
Create tests faster with our browser recorder and converters (JMeter, Postman, Swagger).
Extensive documentation, awesome community and first class support.
Powerful Scripting
No XML. No DSL. Just familiar scripting with ES6 JS
import http from 'k6/http';
import {check, sleep} from 'k6';
export default function() {
const data = {username: 'username', password: 'password'};
let res = http.post('https://myapi.com/login/', data);
check(res, { 'success login': (r) => r.status === 200 });
sleep(0.3);
}Still stuck with JMeter?

What our users are saying
Code-driven, JavaScript load tests that fit into our existing tool chain, clean APIs, command line so easy to automate and with a flag can run the same load test from the cloud in multiple locations. Haven’t had time to blog about it but k6 came out top of multiple tools tested
Toying around with @k6_io tonight. Pretty impressed with how easy it is to set up (yay @Docker!) and to start building test scripts. Some early results: pic.twitter.com/LGCESvFMlv
So @k6_io is probably my new favourite tool. Super quick to get set up and running load tests 😻
personally using @k6_io and its has helped us quite a lot already. Definitely worth adding to your testing pipeline.
Just discovered @k6_io very nice and simple tool for load testing
Lately I have been using @k6_io for performance testing the RESTful APIs we build and I simply fell in love with it. It so simple and easy to use, i highly recommend it!!
Loving @k6_io for integrating perf tests into @AzureDevOps pipelines. Great documentation, easy to use..
I've been tinkering with load testing recently and discovered @loadimpact. I'm absolutely loving it! I got up and running in minutes. Its UI is intuitive, and being based on JS makes it a breeze to start writing tests. That's not even mentioning the amazing open source k6! 😍
